BRIEF OF LAMU LAPSET WATER COMPONENT

Dated 13th March, 2012

a. location

The Lamu Port-Southern Sudan-Ethiopia Transport (LAPSSET) Corridor Project is a Vision 2030 Flagship Project under the Ministry of Transport.

The proposed New Lamu port site is located in Manda Bay to the North end of the Kenyan Coast, bordering Somalia. Proposed developing area falls within 40°52’00” to 41°00’00” in Easting and -2°13’00” to -2°16’00” in Southing.

The main Port is located on Mokowe mainland in Magogoni area (About 2km downstream of Mokowe Jetty) with the resort city extending to Mokowe Mainland, Manda Island and Lamu Island.

Mkanda channel connects Lamu and Manda bay to the South of the proposed site. The channel is very narrow and is mainly used by small boats to access the smaller island within and past Manda bay.

b. Water Sources within the vicinity of the Proposed Port

There is a water supply facility operated by Lamu Water and Sewerage Company serving Mokowe and the Navy Base at Magogoni. The source is two (2) boreholes at Chomo Swamps approximately 20 km from the proposed port site. The two (2) boreholes produce an average of 200m3/day

Hindi Aquifer (swamp) has currently 5No. boreholes operated by a local water users association, supplying Hindi settlement. The boreholes are within the Bele Bele swamp (aquifer) approximately 18km from the proposed port site. The average safe yield of these boreholes is 10m3/hr each.

c. Water Demand ProjectionThe table below has the anticipated water from year 2012 to 2030.

d. Proposed Immediate Water SupplyThe Ministry proposes to drill a total of 10 Boreholes as follows:

(four) boreholes will be drilled in Chomo aquifer, about 20 km from the proposed port site. Based on the current yields of the existing boreholes, the 4 boreholes are expected to yield 259.2m3/day (Each borehole yields 3.6m3/hr)

4 (four) boreholes will be drilled at Bele Bele swamp in Hindi Area, about 18km from the proposed port site. The expected yield of these boreholes will be 1,153m3/day (Each borehole produces 16m3/hr)

2 (two) boreholes will be drilled at Bargoni swamp about 28km from the proposed port site. The expected yield will be 129.6m3/day. (Each borehole produces 1L/Sec.)

The new system will thus produce about 1,400m3/day. The expected yield will thus meet the 1st stage of intermediate demand of 1,200m3/day. The supply will have one booster station and three steel elevated tanks placed on platform ranging from 10m to 20m.

The projected cost of these immediate measures is estimated at Kshs 338,001,675.

However, due to the large investment required, the Ministry of Water and Irrigation intends to Phase the Project into two Phases as follows:-

Phase 1:- Will deal with obtaining water from immediate vicinity of the Port by obtaining water from Chomo Aquifer and transmitting to the Port. Chomo Aquifer is the nearest to the Port and is located about 20km away and some facilities already exists like Treatment Plant, Power, some pipework, Storage and pumping station

Phase 2:- Will involve going afar to new sources at about 35km at Bargoni and 18Km at Hindi Aquifer. This is a major Aquifer which is being underutilized. It has a potential of 6,000m3/day against current abstraction of about 500m3/day. Furthermore, it is located in Prison Farm, a Government Institution.

The tables below have the details.

e. Achievements by the Ministry of Water and Irrigation to dateWater

Immediate Water Supply

The following are the achievements:-

1. Detailed Design of the Intermediate works and Feasibility Study for future and ultimate periods of 2015, 2020 and 2030 is complete. Preparation of Construction Drawings is about 50% Complete.

Design Drawings for the pipe work from Main Booster Station to Lamu Port is complete and has already been issued to NWPCC for implementation.

Survey for line from Hindi to Main Booster Station and additional lines from drilled boreholes in Chomo to the existing 55m3 steel elevated tank is complete and is undergoing design.

2. Drilling of the five of the ten boreholes with estimated cost of Kshs 20million is complete. Two Boreholes have been drilled in Hindi and three in Chomo.

However, test pumping and qualitative analysis is required to determine there yields and portability.

3. Hiring of a Consultant to undertake Water Resource Assessment in the radius of 50km of the Port is in advanced stages.

4. Delivery of about 1,200 pieces of dia. 225mm UPVC Class E pipes for the main gravity main from main booster station to Lamu Port is complete.

However, laying is being hampered by lack of fuel for the excavators for the last two weeks which requires additional payment of delivery charges from Malindi to Lamu which was not cartered for in the initial purchase. NWPCC is trying to top the required delivery charges to the merchant to ensure that excavation and laying is from early next week.
